DEVICE FOR USE WITH RUBBER-THREAD-WORKING MACHINES.

Application filed December 26, 1924., Serial No. 758,175.

To all whom it may concern:

Be it known that I, WILLIAM J. MAnoNnY, a citizen of the United States, residing at Ansonia, in the county of New Haven and State of Connecticut, *have invented a new and useful Improvement in Devices for Use with Rubber-Thread-Workin Machines; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-

Fig. 1 a face view of a rubber-post for a braiding machine, showing my lmproved safety device.

This invention relates to improvement in with rubber-threadworking machines, whether those machines be in the form of braiders for covering one or more strands of rubber thread with fabric, or in looms in which .a number of threads are woven to form a flat web. In the manufacture of'elastic-textile goods, the rubber threads are wound under tension on spools commonly called warp beams. The rubber is generally wound in parallel rows to the required depth, the'number and size of threads depending upon the nature of the material to be produced. In weaving and same, partly in braiding rubber threads, there will be a certain amount of breakage of the rubber threads as the said rubber threads are woven threads, of

or braided under tension. While this breaking may occur at any place on any thread, it is most likely to occur at the place where the actual braiding or weaving action takes place and, in the case of weav-- more frequently in the edge, thread, or

is breakage the web. When t difiiculty is' experienced 1n astakes place,

thread on the beam has v certaining which Preferably and as broken, and diificulty is experienced in rethreadlng the broken strand. The object of this invention is to provide a device so located as to be visible to the operator and which may also actuate electrically a visible or audible signal, or both, and if desired, in addition thereto, to actuate a stop motion for the machine,-and the invention consists in the construction as hereinafter described and particularly recited in the claims. I

In Figs. 1, 2, 3 and 4, I have illustrated my invention in connection with the socalled rubber-post of braiding machines of usual construction. The post '10' is of usual construction, mounted upon the usual carrier-plate, .not shown, and provided at the upper end with a grooved roller 11, over which the rubber thread passes. -This post is segmental in cross-section and the thread passes upward through the base 12, which is provided with a clearance opening 13. Pivotally mounted in the groove of the post is a tubular clamping-member 14, and secured to the screw 15, by which the tube is mounted, is a coiled spring 16 attached to the lower end of a latch-block 17, in the ,form of a bead, and adapted to closely fit the upper edge of the clamping-tube 14:. The screw 15 is insulated from the st.

The inner end of the clamping-bloc is preferably slightly grooved, so at, if desired, during the adjustment of the ma chine, the block can be moved over one side of the clamping-tube, so as to be temporarily mounted thereon. A rubber thread the latch-block 17 down into the upper end of the tube and grip the thread against the upper edge of the tube, as shown in Fig. 4 of the drawings, and the edge in position will be immediately visible to the operator. shown, a yoke 19 will be secured to the back of the post, ,with its ends extending outward on opposite sides of the clamping-tube. The screw 15 is connected by wire 20, which extends down through a perforation 21 in the post and downward through the clearance opening 13, to a visible or audible signal, or to any of the wellthe release of tension known ,forms of stop mechanisms. When the thread breaks, the clampin -tube will engage with .one of the ends 0 the yoke, and so close electrical connection to the signals orstop mechanism, and the broken thread is readily located, and is in position for readjustment to the braiding mechanlsm.

In Figs. 5 and 6 of the drawings, I have indicated the use of my invention to a loom for forming flat web, and in this case, I mount a bracket 22 upon the frame 23 of the loom and below the strands 24 of rubber, which are drawn from the usual warp beam 25. Supported by this bracket, upon a transverse supporting-pin 26, are a series of clamping-tubes 27 like the tubes 14 p viously described, and in each is a springactuated latch-lock 28. Extending acro$ the bracket, beneath the clampin -tubes, is a metal rod 29, insulated from the bracket and adapted to have an electric wire 30 connected with it, this wire running to a visible or audible signal or stop mechanism. Preferably, the threads 24 will pass beneath the supportingin 26. If one of the various threads 24 reaks beyond the bracket 22, on the thread will draw the latch-block 28 into the outer end of the tube 27 and grip the thread, and the tension of the thread will cause the tube to drop into contact with the rod 29 and so close an electrical circuit to a visible or audible signal, or to the stop mechanism or all of them, and the droppmg, of the tube will be readily perceptible to the o erator, so that the broken thread is at once ocated.

In any use", as shown, of my invention,- the breakage of a rubber thread adjacent to the braiding or weaving mechanism is at once noted, and the broken thread is held at a position convenient for re-adjustment.

I claim:

1. In a rubber-thread-working machine, a clamping-mechanism through which a rubber thread may freely pass 1n one direction and adapte when the tension on the thread is released, to hold the thread against movement in the opposite direction, and means operated by the movement of said clamping mechanism to actuate a signal.

2. In a rubber-thread-working machine, a clampmg-tube through which the thread extends, and a clampin -block connected with the tube and adapt when the tension on the thread is released, to gri the thread against the edge of the said-tu e.

3. In a rubber-thread-working machine, a

'nected with said tube and tension on the thread is released, to gr1p the 96 clamping-tube through which the thread extends, and a s ring-actuated clampin -block connected wit the tube and adapte when the tension on the thread is released, to grip the thread against the edge of the said tube.

4. In a rubber-thread-working machine, a

clamping-tube throulgh which the thread extends, a clampin b ock connected with the tube and adapte when the tension on the thread is released, to grip the thread against the edge of the said ,tube, and means operated b a signal.

5. In a rubber-thread-working machine, a clamping-tube through which the thread ex tends, a clampin -block connected with the tube and adapte thread is released, to grip the thread against the edge of the said tube, and an electrical circuit closed by the movement of said clamping-tube.

6. In a rubber-thread-working machine, a clamping-tube throulgh which the thread extends, a clampin ock connected with the tube and adapte when the tension on the thread is released, to grip'the' thread against the edge of the said circuit connected with a sto mechanism and chased by the movement oi said clampingtu e.

7. In a rubber-thread-working machine, the combination with the a clamin -tube pivotall with and through which passes, a clamping-block connected thereyieldingly conadapted, when threadagainst the end of the tube. 8. In a rubber-thread-working machine, the combination with a rubber-post of a clamping-tube ivotally connected thereto, a clam ing-bloc yieldmgly connected with said tu e and ada t'ed'to seat upon the upper end thereof, a yoke connected with the 0st and projectin forward on opposite sides of the tube, t e said tube electrically connected with a adapted, upon the release of tension of the thread, to move into engagement with said yoke, whereby the CiI'ClIlhtO the indicating means is closed.

In testimony whereof, I have signed this 110 specification in the presence of two subscribing witnesses.
